This work presents a single-chip battery-less neural recorder with 12 on-die microelectrodes. It can be powered wirelessly up to 16 cm away from a horn antenna at 915 MHz and only consumes 104 μW\mu \text{W} dc power for accessing ten enabled recording sites simultaneously, transmitting at 5 Mb/s. The implantable device integrated with a flexible antenna weighs only 0.43 g. In vivo measurements on an unrestricted mouse have been successfully conducted, showing response to visual stimuli.

具有片上微电极阵列和集成柔性天线的 0.43 g 无线无电池神经记录仪



这项工作提出了一种带有 12 个片上微电极的单芯片无电池神经记录仪。它可以在距离喇叭天线 16 厘米处以 915 MHz 进行无线供电,并且仅消耗 104 μW\mu \text{W} 直流功率,即可同时访问 10 个启用的记录站点,传输速度为 5 Mb/s。集成柔性天线的植入式设备重量仅为 0.43 克。已成功对不受限制的小鼠进行体内测量,显示出对视觉刺激的反应。
